VILLIAM H. TAYLOR, OF RICHMOND, VIRGINIA.

V oAR-AxLE Box.

SPECIFICATION forming part of Letters Patent No. 242,715, dated June '7, 1881,

Application filed February 25, 1881. (No model.)

The object of'my invention is to prevent jour! nals of car-axles from heating, and thus avoid the risk of danger and injury resulting from hot boxes on railroad-trains. For this purpose I provide for retaining Water in contact with the box on one or more sides to dissipate the heat arising from friction.

My invention consists 1n an axle-box formed with vvater compartments or spaces, as hereinafter described and claimed.

In the accompanying drawings, Figure l is a side elevation, partially in section, of a caraxle box embodying my invention 5 and Fig. 2 is a cross-section of the same.

Similar letters of reference indicate corresponding parts.

A is an axle-box, of usual shape, and of ordinarT size or larger, as the case may require.

B is the axle, a the journal ot the axle, and b the bearing-block.

The box A is formed with two vertical partitions, c c, which form two tight compartments,

d, for containing Water, one at each side of the middle compartment, that contains the block b and packing. The Water-compartments are accessible from the top, and are preferably left uncovered, so that the water can be poured in from time to time, as required. It will be seen that the Water is thus retained in contact with the sides of the journal-compartment., so that in case the journal begins to heat the water will absorb the heat, and so long as there is Water in the spaces the journal will be kept comparatively cool. In case of heating on account of there being no Water in the box the box will be rapidlycooled byreillin g the spaces.

The size, location, and number of the Waterspaoes may be varied Without departing from the scope ot' my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The axle-box A, formed with partitions cbetween its sides, whereby water-tight spaces d are provided at opposite sides ofthe central oilspace, substantially as shown and described.
